Latest Patents
One of Maekawa's latest patents is a lubricating device for power transfer systems. This device is designed to lubricate various parts of a vehicle's power transfer system. It features a gear that interconnects with an output shaft, splashing lubricating oil within an oil chamber. The splashed oil is collected by a cover member and directed to a passage that supplies lubricating oil to a bushing, which supports the output shaft. This design ensures that even if the direction of the splashed oil changes due to varying operating conditions, the cover member effectively captures and supplies the oil.
Another significant patent is the 2-wheel/4-wheel drive switching apparatus. This invention reduces the rotational speed of a motor using a worm gear and a worm wheel, transferring the reduced rotation to a first pinion gear. The apparatus includes a first moving plate that moves along a pair of shafts, with a second moving plate inserted into the same shafts. The system utilizes coil springs to accumulate force during the switching process between 2-wheel and 4-wheel drive modes. This innovative mechanism allows for smooth transitions between drive modes, enhancing vehicle versatility.
